How many of you leave your iPhone on a charger overnight?
OOOHHHH , Wait What! Hold Up, You’re charging your phone overnight, Yes I’m guilty as well
Apple says if you want to preserve your iPhone’s battery, don’t charge it up too much.
The company says charging your iPhone overnight or for long periods of time can actually be bad for it, thanks to its lithium-ion battery. Leaving your phone on the charger forever erodes its power supply faster.
BestLife explained that “your phone’s battery can expect to have a shorter lifespan the more time it spends close to 100 percent.” Yeah, I’m confused, too.
Android users, you’re not out of the woods, either. A cellphone expert told USA Today to “not leave your phone connected to the charger for long periods of time or overnight. Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.”
